Ownership structure and the performance of firms: Evidence from France*

This paper deals with the influence of ownership structure, variables of external and organisational discipline on financial and economic performance. By means of self-organising maps, in particular Kohonen maps, we highlight three main results. Firstly, the results obtained from a sample of French companies are consistent with the findings of Morck, Shleifer and Vishny (1988), McConnell and Servaes (1990) and Short and Keasey (1999) and suggest a non-linear relation between ownership structure and performance. Secondly, the variables of external discipline, that is leverage and stock-turnover, partly explain performance. Although debt level negatively influences perform- ance (Opler and Titman, 1994), conversely, stock-turnover has a beneficial impact on performance (Charreaux, 1997). Finally, though the organisational variables seem to have no significant impact on performance, corporate size has a positive influence on performance.
